__NSCFConstantString objectForKeyedSubscript: unrecognized selector sent to instance 0x100003680
0x01直接上代码
NSDictionary *dic = @{@"views":@[@{@"tag":@"100"},@{@"tag":@"200"}]};
for (NSDictionary *subDic in dic) {
NSString *key = [NSString stringWithFormat:@"%@",subDic[@"tag"]];
NSLog(@"key:%@",key);
}
subDic 控制台输出的内容是：views.
0x02结论
1.要遍历是应该是views对应的value(数组)。
2.对一个字典进行遍历时，取到的是key。
